I mea e pale aku ai i ka pilikia o ka LED, pono e hana ʻo OKES i kahi hana maikaʻi i ka hoʻokele maikaʻi ʻana o ka hemahema o ka welding a me nā ʻāpana ʻāpana, hana i ka hoʻāʻo ʻelemakule ma nā huahana LED, a hōʻoia i ka hilinaʻi o nā huahana uila.He hana koʻikoʻi kēia i ke kaʻina hana huahana.I ka wā o ka ʻelemakule, aia nā hoʻokolohua hoʻololi ʻana i ka wela, ka ʻāpana volta analog (kiʻekiʻe, waena, haʻahaʻa), ka hoʻāʻo ʻana i ka hopena, a me ka nānā ʻana i ka pūnaewele o ka lako mana hoʻokele, nā huahana i kēia manawa, nā loli uila a me nā ʻenehana ʻē aʻe.

ʻO LED, ma ke ʻano he kumu ikehu hou o ka ʻenehana mālama ola, e hōʻike i kahi pae o ka attenuation māmā i ka wā mua o ka hoʻohana ʻana.Inā maikaʻi ʻole kā mākou huahana LED a ʻaʻole i hana ʻia ma ke ʻano maʻamau i ka wā o ka hana ʻana, e hōʻike ana nā huahana i ke kukui ʻeleʻele, ʻālohilohi, hāʻule, nā kukui intermittent a me nā mea ʻē aʻe, e hana ana i nā kukui LED ʻaʻole lōʻihi e like me ka mea i manaʻo ʻia.
